Be it known that L'Trroims' SniivnRs, a citizenof the United States,residing at Uskaloosa, in the county of Mahaska and State of Iowa,haveinvented a. new and useful EX- cavating," Dumping, and SpreadingMachine, of which the following is a specifica tion.

This invention relates to that class of machines sometimes known asexcavating cart".

Objects of the present invention are to provide a machine which willexcavate earth duringthe. forward traveling of the machine, carrytheexcavated material intoa hopper or receptacle, transport the materialto the desired point, dump the material either as amass or by degrees,and if de sired spread the dumpedmaterial or level it to grovide acomparatively smooth surface.

ther objects are" to provide a machine of the indicated character,which, after the hopper is filled with the excavated material, maybeused as a carrier and duinper without having recourse ito the spreadingor levcling means;

More specific objects are to provide a novel means for conveying plowedearth as it is broken by the plowfrom the ground to a point above ahopper; and to provide improved means for positively forcing the earth,so lifted, into the hopper and then distributing it so that the hopperis filled evenly on ll sides.

Further objects are to provide means whereby the element which lifts theearth may be freed from or cleaned of said earth when the machine is tobe no longer used;

to provide an improved spreader, and leveler; and in general to effectadvances in the :state of the art to which the present machine belongs.

The invention will be best understood from a considerationof thefollowing detailed description taken in connection, with theaccompanying drawing forming part of this specification, with theunderstandrng,

however, that the invention is not confined to any strict conformitywith the showing in the drawing, but maybe changed and modified so longas such changes and modifications mark no material departure from thesalient features of the invention as eX-.

pressed in the appended claims. g

In the drawing I Fig. 1 is a side elevation, with parts in section, of amachine representing an embodiment of the present invention.

Fig. 2is top planview of the same.

8 is a front elevation with parts of the frame in cross section.

Big. 4 is a vertical transverse cross sec-- tion through the centralpart of the machine. V

ig. 5 is a detail elevation showing part of the control means fordumping the terial.

I Fig. 6 is a detail view showin the means for holding the excavatedmaterial in the earth-elevating wheel and the control levers therefor.

In the drawing wherein is shown a preferred embodiment of the. inventionby way or illustration, the numeral l0 designates the main frame of themachine, the forward endv of which is suitably fashioned so that draftappliances may be hitched thereto. The presentmachinc is well adapted tobe pulled by atractor and the frame should be constructed accordingly.Mounted upon the frame 10 is a hopper or receptacle 11 provided withcut-out sections 11 and 11 on opposite sides at the top thereof for apur pose to be described. Thishopper or receptacle is open at the topand hasits sides converging somewhat downwardly so that the bottom ofthe hopper is of smaller area than the top. Passing through the hopperis a sleeve or housing 1 which encloses an axle. Fast to one end of theaxle is a conveyer wheel 14, and loosely mounted on the opposite end oftheaXle is a second wheel 13 of ordinary construction. The two wheelstogether support the cartand at the same time allow the cartto turnreadily.

The elevating wheel 14 has a considerably ,wider tread or rim than hasthe wheel 13 and built into this tread is an annular elevatin oocketwhich forms an im nortant part the present invention. This pocket 17 isprovided by a wall at right angics to the tread or run of the wheel andinside the latter, in conjunction with an annular straight wall 15,,andis of sufiicient width that its outer r free end will nicely fit thepocket at its point of least width. The scraper 18, as seen in Fig. 1,also extends rearwardly relative to the vehicle so that its free endengages with the wall 15 before its lower edge engages with the wall 16;

Thebotton'i'of the hopper ll is closed by hinged doors 19 openingdownwardly: Said deer are maintained in closed position by chains .20secured to a shaft 22 mounted in brackets 21 and. extendinglongitudinally of the'inachine above the hopper. As the-shaftis'rotated'by means to be-described, the chains 20 will be wrappedaboutthe shai't, thus bringing thedoors 19 to closed position, or elsethey will be unwrapped therel roin, whereuponthe doors will swingoutwardly to dump. the material. I V

' The clorward end of the shaitBQ mounts a hand wl1eel 23. rJspring 2%similar to a clock spring is securechat one end to the shaft 22 andis'housed within a recess pro vided on a ratchet disk25 'on wheel 23 andhas its outer end secured to said disk. A pawl 26 is pivotally mountedupon the;hop per,asindicated at and has a handle 28 normally maintainedin raised position by a coil spring 29, The spring 29 tends to n aintain the pawl inengageinent witlrthe teeth of the ratchet disk.Thespring "24: tends to THOR Gille shattQiZ in such direction-that thedoors 19 are niaintainedin closed position,

and itthere is no material in the-hopper, sale springwnl keep sa ddoorsclosed. The

dumping of the load winds up the spring 24', s

said dumping; being allowed to; take place only when the pawl is swung;out ofengagenientwith the ratchet disk. After'the load isduinped, thetension of the spring returns the doors to closed position and the pawl,being springpressed against theratchet, holds the disk and henee theshaft 22 in the necessaryposition so that moreexcavated rial may beconveyed into the cart and held therein until] thetiine for the nextdumping occurs. a

' Secured to the torward end of the "frame near the top of the hopper isan arcuate bar Bdhnving one'kn: more notches therein.- A. hand lever 31swings over the notch bar and is noruia-lly maintained in apositionalinost upriohtlw a spring 352'. .he lower end of the leyer V onthe under ll'itlnfi 10, and anarin 34 is so sccured to tie leverBl thatforward movement ol" said lever lifts the free end oi the arm. At saidireeencha disk plow 35 is mounted, said disk plow being in adjustedThis, scraper not only engages 31 'is pi\ 'oted, as indicated 'at 33,

motion linkage." By this means spreader or leveler, when raised or lo'ered position. to the wheelll l and so positioned th'atthe plowed-upearth is thrown into the annular pocket 17. As will be noted, the diskplow 35 is set in advance or the lowest vpart of the wheel 14. Thetendency of spring 32 will be to hold the plow into the ground. 'lVhenitis desired to lift the plow, as when theinachine is being used totransportthe excavated' rnaterial, the lever 31 will be moved until itsdetent or dog engages with a notch of the arcuate bar 30.

'Secured upon the outside or" the hopper and between the hopper and thewheel 1% is a plate having a depending hinged leaf l 'he'plate andits-leafeover the elevatmg pocket l'i tor a distance less than halfthe'circuinierence of the wheel l t. The rod 38 has a crank 39 iorinednear one end theieof engagii'ig'with suitable elements provided on theleaf 37'so that oscillationol' saidgrod will cause'swinging oi the leafon its hinges; or, in other words, toward and from the inner :taee ofthewheel 1%. To effect this'oscill'atiointhe rod SS-is supported in bear-i141 onithe underside of-the'fraine 1'0, and a lever is fixed-at theforward end oi -said rod; Thelower partof the leaf 3'7 is disposed tothe rearoi the lowest part 01 the wheel- 14: and therefore also totherear of thepdisk plow 35. V p

Secured to the hopper, and extending across the topof the same in alongitudinal direction, is a bar 2L2 providing a-support tor-adistributing wheel including a b and arinsfl l. Said arms extendbetweenthe spokes 'olF't-he'wh'eel IB 'wherehy the distribwheelisturnedduring' thefadvance of the 1 achine; Said distribut ng wheel isdie signed to take the earth deliveredby the elevating" wheel and spreadit" eienly over the interior of the hopperso that the earth will notpile up on theside of the hopper where the scraper 1S is provided. l

force theearth intothehopper. The angle of re aose'of loose earth is an)IOXllililtGl indicated by the line It, ll in Fig. 1, but the rotationof the wheel in comb nation with theoackm of the earth into the. pocket7 caused by the disk plow, changes this angle of r poseuntil itassumesapproximately the inclination of thehne L, L. This change in athe angle'of repose effected by the constant packing of :fresh'earthintothe circular ele vating pocket is sufficient to allow the earth to becarried in a more or less compactmass, upwardly until it is opposite thecutaway portion 11 in the hopper, where the scraper cleans the pocketout. T he earth travels in a continuous stream from the disk plow aroundthe semi-circumference of the pocket,

into the hopper, past the scraper which also acts as a shield andprevents any of the earth from being carried around to the ground again.
